Hi all.
Need some advise on my encounter. Maybe hard to explain so pls bear with me
I order a 1.67 Crizal Advan with frame. My degree is around 700+/eye
I went to collect my spect today. There is this weird problem I experience. Need an example to explain:
Assuming I am on this new pair of specs and look at nothing but a square. If i move/nod my head downwards but eyes are still fixing on the square, what I will see is the square will be "distorted" and become a rectangle. if I look upwards, the distortion isnt that significant but still there.
After doing some experiments with the optician, we noticed that
1) the frame design actually tilt the lens to be not parallel as your surface of my eyes but slated in the sense (if u look at the side of the spec) that the upper part of the lens protruding out more than the lower part of the lens.
2) He claimed the sharpness of the lens is clear and perfect, based on some machine he used with has this circular monitor like an target. Dunno what u call that.
3) Due to my new lens being smaller than my current one (to be more precise, the width is in fact smaller but length is abt the same as my current old one), such problem may exist. He also claimed that the position of my nose and face shape (yes...he mentioned that) may have contribute to the phenomenon.
4) I have no such problem using my current specs. And it is not a Crizal but some Japan brand which i cant rem. One thing to note though, my current old lens is boarder (aka the width is longer) compared to my new lens.
So what you guys think? It is a manufacturer fault (as in the Crizal lens) or its a normal sight to have distorted images? Anyway, the optician is kind enough to allow me to change to another frame which dun have this slating problem of the lens. But I cant be very sure if the lens do not contribute to the sight i observed. The new spec will be ready by end of the week...
TIA!
